WILLIAM I-I. I-IADAWAY, OF KENNESAW, GEORGIA.

To @ZZ whom @'25 may concern Be it known that I, IVILLIAM I-I. HABA- wAY, a citizen of the United States, residing at Kennesaw, in the county of Cobb, State of Georgia, have invented certain new and useful Improvements in Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Ihis invention is directed to improvements in locks, and has for its object to construct a device of this character in a simple manner, but at the same time producing a lock which is absolutely burglar proof.

W ith these and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter fully described and claimed.

In the drawing: Figure 1 is a side elevation of the lock with the bolt withdrawn, the cover plate being removed. Fig. 2 is a similar view, the bolt being projected. Fig. 3 is a sectional view on line 3 3 of Fig. 1. Fig. 4 is a sectional view on line 4 4 of Fig. 1. Fig. 5 is a side elevation of the lock, the cover plate removed, and showing the parts reversed, the bolt withdrawn. Fig. 6 is a similar view, showing the bolt projected.

Referring to the drawing, the numeral 1 designates the casing, the same being provided with upper and lower channels 2 and 3, respectively, said channels being arranged transversely of the casing 1. Arranged vertically in the casing 1 is a pair of parallel spaced channels 4 and 5, the lower ends of which open into the channel 3, while their upper ends intersect with the upper channel 2 and terminate in pocket-s 6. Slidably mounted in the lower channel 3 is a bolt 7, the upper edge of which is provided with a pair of seats 8, the same being spaced apart so as to be out of registry with the vertical channels 4 and 5 when the bolt is withdrawn and held in its withdrawn position by the tumblers 9. The tumblers 9 are slidably mounted in the channels 4 and 5 and have their upper ends formed with recesses 10, the resultant lugs 11 being adapted to engage in the pockets 6, when said tumblers are operated to release the bolt 7.

Formed in the casing 1 and between vthe Specification of Letters Patent.

channels 4 and 5 is an inverted V-shaped recess 12, and in which a leaf spring 13 operates, said spring having its upper end secured in a slot 14 formed in the casing 1. The bolt 7 is further provided upon its upper edge with a slot 15, the lower end of the spring 18 being engaged in the slot 16, thus holding the bolt 7 in its withdrawn position, as shown in Fig. 2.

Adapted for insertion in the channel 2 is a key 17, said key having formed upon its upper edge a pair of spaced lugs 1S, said lugs being adapted to engage the lugs 11 formed upon the tumblers 9. To limit the inward movement of the key 17 the same is provided with shoulders 19, which engage one edge of the casing 1, said key being further provided with a handle 20.

From this construction, it will be seen that when the key has been inserted in the channel 2, and it is desired to project the bolt 7 to engage the keeper 21, it is only necessary to force the bolt 7 inwardly, whereupon the tumblers 9 will move downwardly and engage the seats 8, thus locking the door. Upon moving the handle upwardly the tumblers will be disengaged from their seats thereby permitting the bolt 7 to slide outwardly under the action of the spring 13 to disengage the keeper 21, thus unlocking the door. It will be noted that the bolt 7 is of such length that the ends thereof project slightly beyond the edges of the casing 1, so that the outer end may be engaged to force the bolt in engagement with the keeper, and at which time vthe tumblers will drop into the seats S formed in said bolt to hold the same in its locked position.

In Figs. 5 and G, the parts forming the lock are shown in a reversed position, the spring 13 being engaged in the slot 15, and at which time the lock may be applied to a door having the keeper plate carried upon the right side of the door frame, it being of course understood that the position of the key 17 is reversed, and as clearly shown in the said figures.

What is claimed is:

The combination with a casing, the upper and lower horizontally disposed open ended channels formed in the casing, vertical channels formed in the casing, a bolt slidably mounted in the lower channel, seats formed in said bolt, tumblers slidably mounted in the vertical channels and adapted to engage said seats, to hold the bolt in its looked position, a recess formed n the casing, a leaf spring operable n said eoess, a slot formed in the bolt, said spring having tslowey end engaged in said slot to move said bolt n one direction, a key adapted for insertion in either end of the upper channel for operating the tumblers to successively dsengagel the seats in the bolt, as and for tbe purpose set folfth. 10 In testimony whereof, I afHX my signature,

in presence of two Witnesses.
